Ice World at 415K - ??

Maybe frozen iron, could that be classed as ice?
141 degrees C is indeed warm but that's a global average temp. It's not necessarily that hot all over.
It's rotating, so the dark side is bound to be very cold.
I expect that the water ice sublimates during the day and then snows back down during the night.
At 2G any sublimated water vapor would stay close to the ground I think.
That should mean that any impact craters would be smoothed over, but this is a game and doesn't model erosion like this.
The description says "composed mainly of water ice"

Frozen Iron is what we just call Iron. 415K isn't hot enough to melt iron.

What Major Klutz said. It's entirely possible the water ice is several KM underground and under high pressure. With a temp of 415k, the water will always be ice if the pressure is more than (approx) 100 kbar.

It's definitely not possible, Stellar Forge was indeed drunk with these Planets.
There's quite a few of such bugs.
The surface of these landable (!) Planets clearly indicates a solid, Icy crust and surface you can safely land on.
Which doesn't make any sense, since Ice does not remain solid on the surface and at zero Pressure at these Temperatures. And if the Surface Temp is the average, it would mean we're talking 500+ K or more on the daylight side.
These Planets' Gravity is grossly insufficient to create the pressure required to keep Surface Ice from transitioning into fluid (or more likely : Gas), especially with no atmosphere protecting that very surface from the nearby Sun.
Such a Planet would rapidly evaporate its Ice and lose most of its Mass into space, eventually leaving nothing but its Rocky or Metallic core exposed to the forces of the Solar particle stream - or become a Planet with a very dense Atmosphere inhibiting that process at some point.
But if anything, these Stellar Forge quirks give us something unusual to look at and take note of. That's fairly rare

Except this Planet is landable and lacking a few ten thousand Atmospheres to qualify for "hot ice". That was my whole point.
But at 2G it wouldn't lose much if any mass into space, especially if it has a magnetic field.
141 degrees c is not really that hot. Any ice that melts and evaporates during the day will condense and freeze again at night.

The airlessness is not realistic, but the hot ice planet is a widely accepted thing in the astronomy world outside our Elite galaxy.
I think Frontier added airless variations of all kinds of planets just to make future content easily accessible. Unfortunately, none of these airless planets have since been made available to us. Be it, waterworlds, ammonia worlds or lava worlds.

Thanks for the great feedback Commanders.
I suppose I should at least have landed, but I was in my 'must now get home' frame of mind
I do look forward to the time when we can land on planets with an atmosphere - in this case, had there been an atmosphere it would have been interesting and a huge contrast between the 'dark' and 'light' sides ... one day

Just did a EDDB Dump on the hottest 0 Atmosphere and landable Icy Planets.
System: Qoefi LU-D d13-53
Distance to Sol: 45,304.31 ly
Distance To Arrival: 16 ls
Is Landable: Yes
Terraforming: Not terraformable
Earth Masses: 57.3840
Radius: 23,874 KM
Gravity: 4.09 G
Surface Temperature: 1,548 K
Volcanism: No volcanism
Atmosphere: No atmosphere
Orbital Period: 1.9 D
---------------
Hehe, that thing literally would instantly burst into a frenzy. The whole darn Planet would be nothing but turning into a huge Geyser Volcano so close to its F9 VB Star
Luckily it's still missing quite a bit Temperature for its Ice i.e. to enter thermal decomposition into Hydrogen and Oxygen - and become literally explosive xD

It is possible last I checked, I can't remember the specifics or to which degree it is possible, but there are such a thing as hot ice worlds, if there is enough pressure and such, so yeah, maybe? but would be insanely volatile.
Which could be kinda cool, you know, imagine a planet you can land fine on shadow side, but once sun hits surface, you'd have gigantic eruptions and liquids everywhere.

Thanks for the interesting comments.
The thing about this was, it is an ice world, with no atmosphere, so it shouldn't really work ...
"hot ice worlds" without atmospheres (as they are presented in ED) are not physically possible. if an ice world migrated in from the outer system its surface would melt and either be lost to space (if low mass) or the gases released would be retained as an atmosphere (if the world is sufficiently massive to retain one), which would insulate the surface and you'd probably end up with a 'steam greenhouse' world with a global atmosphere and ocean.
So this is Stellar Forge being drunk again.

Wouldn't it be possible for the sublimated gasses to condense and re-freeze on the night side?
Even Mercury's night side is cold enough to freeze water. Sublimated water vapor would surely condense and re-freeze if gravity could keep it from leaving the planet alltogether.
If the planet is high gravity, wouldn't the gasses stay close to the surface? If the planet had a strong magnetic field (something ED doesn't mention in a DSS) it would be shielded from ionizing particles that might strip away the atmosphere. If it's cold enough for the atmosphere to re-freeze at night, it would never be able to build up much of an atmosphere.
Alternatively, a lightweight planet could be losing all of it's atmosphere to space every day resulting in a mostly airless world constantly sublimating into space and shrinking until there's nothing left but a rocky core.
No idea how long that could take, but it could exist for some period of time I think.
